jetty jsp 404 not found

内嵌Jetty服务器,启动后访问jsp页面,显示404 NOT FOUND。

源代码如下:

package soc.main;

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletHolder;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.glassfish.jersey.servlet.ServletContainer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;

import soc.config.ApplicationApi;
import soc.config.SpringJavaConfiguration;

public class SocMain {
	public static void main(String[] args) throws Exception {

		ApplicationApi applicationConfig = new ApplicationApi();
		ServletContainer servletContainer = new ServletContainer(applicationConfig);
		ServletHolder jerseyServlet = new ServletHolder(servletContainer);
		ServletContextHandler context = new ServletContextHandler();访问jsp会404
		

		context.setClassLoader(Thread.currentThread().getContextClassLoader());
		context.addServlet(jerseyServlet, "/rest/*");

		context.setContextPath("/");
		context.setResourceBase("src/main/webapp");
		context.addEventListener(new ContextLoaderListener());
		// context.addEventListener(new RequestContextListener());

		context.setInitParameter("contextClass", AnnotationConfigWebApplicationContext.class.getName());
		context.setInitParameter("contextConfigLocation", SpringJavaConfiguration.class.getName());
		int port = 8080;
		if (args.length == 1) {
			port = Integer.parseInt(args[0]);
		}
		Server server = new Server(port);
		server.setHandler(context);
		try {
			server.start();
			server.join();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

出现这一问题的原因是:context要使用Jetty-webapp 包下的WebAppContext,使用jetty-servlet 包下的ServletContextHandler则会导致访问jsp页面not found。修改后的代码如下:

package soc.main;

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletHolder;
import org.eclipse.jetty.webapp.WebAppContext;
import org.glassfish.jersey.servlet.ServletContainer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;

import soc.config.ApplicationApi;
import soc.config.SpringJavaConfiguration;

public class SocMain {
	public static void main(String[] args) throws Exception {

		ApplicationApi applicationConfig = new ApplicationApi();
		ServletContainer servletContainer = new ServletContainer(applicationConfig);
		ServletHolder jerseyServlet = new ServletHolder(servletContainer);
		// ServletContextHandler context = new ServletContextHandler();
		// 访问jsp会404Not Found

		WebAppContext context = new WebAppContext();

		context.setClassLoader(Thread.currentThread().getContextClassLoader());
		context.addServlet(jerseyServlet, "/rest/*");

		context.setContextPath("/");
		context.setResourceBase("src/main/webapp");
		context.addEventListener(new ContextLoaderListener());
		// context.addEventListener(new RequestContextListener());

		context.setInitParameter("contextClass", AnnotationConfigWebApplicationContext.class.getName());
		context.setInitParameter("contextConfigLocation", SpringJavaConfiguration.class.getName());
		int port = 8080;
		if (args.length == 1) {
			port = Integer.parseInt(args[0]);
		}
		Server server = new Server(port);
		server.setHandler(context);
		try {
			server.start();
			server.join();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
